Metaphysics uses empty words, or just produces pseudo-statements [Carnap]
|
|
Full Idea:
Since metaphysics doesn't want to assert analytic propositions, nor fall within the domain of physical science, it is compelled to employ words for which no criteria of application are specified, ..or else combine meaningful words..into pseudo-statements.

From:
Rudolph Carnap (Elimination of Metaphysics by Analysis of Language [1959]), quoted by Tim Maudlin - The Metaphysics within Physics 2.4
|
|
A reaction:
A classic summary of the logical positivist rejection of metaphysics. I incline to treat metaphysics as within the domain of science, but at a level of generality so high that practising scientists become bewildered and give up.

A property is essential iff the object would not exist if it lacked that property [Forbes,G]
|
|
Full Idea:
A property P is an essential property of an object x iff x could not exist and lack P, that is, as they say, iff x has P at every world at which x exists.

From:
Graeme Forbes (In Defense of Absolute Essentialism [1986], 1)
|
|
A reaction:
This immediately places the existence of x outside the normal range of its properties, so presumably 'existence is not a predicate', but that dictum may be doubted. As it stands this definition will include trivial and vacuous properties.

Trivially essential properties are existence, self-identity, and de dicto necessities [Forbes,G]
|
|
Full Idea:
The main groups of trivially essential properties are (a) existence, self-identity, or their consequences in S5; and (b) properties possessed in virtue of some de dicto necessary truth.

|
From:
Graeme Forbes (In Defense of Absolute Essentialism [1986], 2)
|
|
A reaction:
He adds 'extraneously essential' properties, which also strike me as being trivial, involving relations. 'Is such that 2+2=4' or 'is such that something exists' might be necessary, but they don't, I would say, have anything to do with essence.

One might be essentialist about the original bronze from which a statue was made [Forbes,G]
|
|
Full Idea:
In the case of artefacts, there is an essentialism about original matter; for instance, it would be said of any particular bronze statue that it could not have been cast from a totally different quantity of bronze.
|
|
From:
Graeme Forbes (In Defense of Absolute Essentialism [1986], 3)
|
|
A reaction:
Forbes isn't endorsing this, and it doesn't sound convincing. He quotes the thought 'I wish I had made this pot from a different piece of clay'. We might corrupt a statue by switching bronze, but I don't think the sculptor could do so.
